Rev monitor, hard acceleration / brake, high rev and load %

Just started using your health monitor and it’s fine. Didnt recognize my cars vin n. But managed to put the data in manually. I was wondering why the rev range goes up to 6000rpm max. Isn’t there a way to customize this? My car is green till 7k then in red zone between 7k and 9k. For the hard acceleration and braking what are the sensitivity parameters set to? The same goes for high rev. and speeding. Lastly how is the load indicator calculating? Seems inaccurate sometimes.

Thank you!
